CHECK VALVES and GATE VALVES are two common types of valves in industrial piping systems, which are respectively used to prevent the backflow of media and control fluid flow. However, due to the differences in their designs and working principles, there are significant differences in their performance in terms of reliability. This article will conduct a reliability assessment of these two types of valves from multiple perspectives to help users choose the appropriate valve types.

In industrial pipeline systems, it is crucial to select appropriate GATE VALVE materials and pressure ratings. J-VALVES manufactures a wide variety of GATE VALVES that are suitable for various complex working condition environments. This article will compare the recommended gate valve materials and pressure ratings under different working conditions in tabular form to help engineers and purchasers make informed choices.
 

API 600 vs BS 1873: Technical Differences and Selection ImpactWhen it comes to steel gate valves, API 600 and BS 1873 are two major international standards.
